In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Referring to fig. 2, fig. 2 is a first embodiment of the laser sensing-based interaction method of the present invention, which includes the following steps:
in step S10, first coordinate information of the laser spot is acquired.
In this embodiment, the interaction control method based on laser sensing is applied to a terminal device, where the terminal device has a display device, for example: intelligent terminals such as PC, advertisement machine. The display device is configured to implement interactive control based on laser sensing, and the laser sensing layer is configured to receive a laser spot emitted by a laser emitting device to start executing the steps of this embodiment, for example: the user illuminates the display device with the laser transmitting device and starts to perform the steps of this embodiment after the display device senses the laser spot. Specifically, the terminal device is also a hardware device having a computer infrastructure, which can be described by using a von neumann architecture, that is, the terminal device includes an arithmetic logic unit, a control circuit, a memory, and an input-output device, and the laser spot is a bright area formed by focusing a laser beam on a point.
Specifically, after a laser sensing layer in the display device senses a laser spot, since the laser spot sensed by the laser sensing layer is invisible light, and the interactive control is realized on the display device of the terminal device, after the laser sensing layer senses the laser spot, first coordinate information of the laser spot can be obtained; then, second coordinate information of the cursor is obtained according to the first coordinate information and a coordinate range of a preset display area, wherein the second coordinate information is in the coordinate range; and displaying the cursor according to the second coordinate information.
Further, the laser sensing layer may be formed by M × N photoelectric sensors, such as photo resistors, and the X-axis coordinate and the Y-axis coordinate of each photoelectric sensor are obtained by encoding each photoelectric sensor, so that the photoelectric sensors can detect the coordinate information of the light spot. The first coordinate information is coordinate information of a photoelectric sensor corresponding to the laser spot in the laser sensor, optionally, in view of possible inconsistency of the size of the laser spot, when the laser spot corresponds to a coordinate of the photoelectric sensor, the first coordinate information may be selected from the coordinates of the photoelectric sensor, for example: when the coordinates corresponding to the laser spot are (98, 99), (99, 99), (100, 99), (99, 98) and (99, 100), the center point coordinates (99, 99) can be used as the first coordinate information; at present, under an ideal state, the laser facula and the photoelectric sensor coordinate are in a one-to-one relationship.
Step S20, obtaining second coordinate information of the cursor according to the first coordinate information and a coordinate range of a preset display area, where the second coordinate information is within the coordinate range.
In this embodiment, the second coordinate information and the first coordinate information have a corresponding relationship, and specifically, the terminal device may convert the coordinate value corresponding to the first coordinate information into a coordinate value corresponding to the second coordinate information, for example: after the terminal equipment finishes scanning the frame, the terminal converts the coordinate point of the identified laser sensing layer (Sensor) into the coordinate of the display pixel of the screen. It should be noted that the second coordinate information is located in the coordinate range of the pre-display area, and it is easily understood that even if the coordinate value corresponding to the first coordinate information is larger, there is a corresponding coordinate value of the second coordinate information located in the coordinate range of the pre-display area.
And step S30, displaying the cursor according to the second coordinate information.
In this embodiment, the terminal device may generate a cursor corresponding to the second coordinate information on the display device.
In the technical scheme of the embodiment, the terminal equipment acquires first coordinate information of a laser spot; acquiring second coordinate information of the cursor according to the first coordinate information and a coordinate range of a preset display area, wherein the second coordinate information is in the coordinate range; and displaying the cursor according to the second coordinate information. Because terminal equipment accessible is handled the coordinate information of laser light board, can make the user when carrying out the mutual of laser-induced, the coordinate value of laser-induced layer coordinate information all can correspond a screen pixel and show the coordinate value of coordinate information, at mutual in-process, can make the cursor never go out of bounds, consequently, has improved the interactive intelligent degree of laser-induced.
Referring to fig. 3, fig. 3 is a second embodiment of the interaction method based on laser sensing according to the present invention, and based on the first embodiment, step S20 includes:
step S21, determining third coordinate information corresponding to the first coordinate information according to a first preset corresponding relationship and the first coordinate information, where the first preset corresponding relationship is a corresponding relationship between the first coordinate information and the third coordinate information preset in the terminal device, and the third coordinate information is coordinate information corresponding to the first coordinate information and located within a coordinate range of the preset display area or located outside the coordinate range of the preset display area.
In this embodiment, the laser spot is formed by irradiating a laser beam emitted by a laser emitting device onto a laser sensing layer of a terminal device, the first coordinate information is coordinate information of the laser spot in the laser sensing layer, and the second coordinate information and the third coordinate information refer to screen display pixel information, where the second coordinate information is different from the third coordinate information in that a coordinate value corresponding to the second coordinate information is within a coordinate range of a preset display area, and a coordinate value corresponding to the third coordinate information may be outside the coordinate range of the preset display area, the first preset relationship is preset for the first coordinate information and the third coordinate information, and the terminal device may determine the third coordinate information according to the first preset corresponding relationship and the first coordinate information.
And step S22, acquiring second coordinate information of the cursor according to the third coordinate information and the coordinate range of the preset display area.
In this embodiment, when the terminal device determines that the first coordinate information corresponds to the third coordinate information, when determining a corresponding second coordinate information according to the third coordinate information, it is easily understood that when the coordinate value corresponding to the first coordinate information is not within the coordinate range of the preset display area, a second coordinate information different from the coordinate value of the third coordinate information is determined, specifically, for example: when the first coordinate information is A and the corresponding third coordinate information is B, determining second coordinate information C in the coordinate range of the preset display area according to B.
In the technical scheme of this embodiment, since the control of the coordinate information is performed according to the preset corresponding relationship, when the change of the coordinates of the laser sensing layer is large, a cursor is finally generated in the preset display area, and the stability of the interaction of the laser sensing is improved.
Referring to fig. 4, fig. 4 is a third embodiment of the interaction method based on laser sensing of the present invention, and step S22 includes:
step S221, if the third coordinate information is within the coordinate range, using the third coordinate information as the second coordinate information of the cursor.
In this embodiment, the terminal device determines whether the third coordinate information is within the coordinate range of the pre-display area, and further determines whether the third coordinate information is within the coordinate range of the pre-display area.
Step S222, if the third coordinate information is not within the coordinate range, adjusting the third coordinate information according to the boundary coordinate information of the coordinate range of the preset display area to obtain second coordinate information of the cursor.
In the technical scheme of this embodiment, the terminal device determines the coordinate range of the coordinate value of the third coordinate information, and when the terminal device is in the coordinate range of the preset display area, the terminal device can directly use the coordinate value as the second coordinate information without searching for the corresponding second coordinate information, so that the generation efficiency of the second coordinate information is improved.
Referring to fig. 5, fig. 5 is a fourth embodiment of the interaction method based on laser sensing of the present invention, based on any one of the first to third embodiments, step S222 includes:
step S2221, if the abscissa of the third coordinate information exceeds the abscissa limit value of the coordinate range, using the exceeded abscissa limit value as the abscissa of the second coordinate information.
Step S2222, if the ordinate of the third coordinate information exceeds the limit value of the ordinate of the coordinate range, taking the exceeded limit value of the ordinate as the ordinate of the second coordinate information.
In this embodiment, when the third coordinate information is not in the coordinate range of the preset display area, the terminal device may determine whether both the abscissa and the ordinate of the terminal device exceed the coordinate limit value, and further reassign the coordinate information exceeding the coordinate limit value according to the determination result, the abscissa limit value, and the ordinate limit value, for example: screening display coordinates and corresponding coordinate data of the screen, displaying boundary coordinates of coordinates beyond the range of the screen, taking a screen of 1920X1080 as an example: the upper left corner of the screen is (0, 0), the value range of x is [0, 1920], and the value range of y is [0, 1080 ]. The coordinates of x and y are judged during laser driving: if x is less than 0, then x is assigned a value of 0, and if x is greater than 1920, then the value is 1920, and y is the same.
In the technical scheme of the embodiment, the terminal device can clearly determine the object to be assigned through the abscissa and the ordinate of the display pixel coordinate of the determination screen, and then can assign the object, so that when the laser sensing interaction is realized, a cursor cannot go out of bounds, and the user experience is improved.
Referring to fig. 6, fig. 6 is a fifth embodiment of the interaction method based on laser sensing according to the present invention, based on any one of the first to fourth embodiments, before step S20, the method further includes:
and step S40, acquiring resolution information of the terminal equipment, and determining the coordinate range of the preset display area according to the resolution information.
In this embodiment, the coordinate range of the preset display area may be determined according to resolution information of the terminal device.
Optionally, the coordinate range of the preset display area may be further set within the resolution range, for example: for a screen with a resolution of 1920x1080, if the user feels that the resolution is too high, a smaller display area may be set on the screen.
In the technical scheme of the embodiment, the terminal device determines the coordinate range of the preset display area through the resolution of the terminal device, and the resolution information is easy to obtain and convenient to directly call, so that the determination of the coordinate range of the preset display area can be accelerated.
Referring to fig. 7, fig. 7 is a sixth embodiment of the interaction method based on laser sensing according to the present invention, based on any one of the first to fifth embodiments, after step S30, the method further includes:
step S50, an operation instruction for the cursor is acquired.
In this embodiment, the operation instruction may be generated for an association relationship with a cursor, where the association relationship includes a cursor state, and optionally, the cursor state may simulate a mouse, specifically, for example: if the mouse is simulated by double-click, a user can quickly press the switch of the laser emitting device twice within the preset time to realize the double-click operation instruction and the click operation. Optionally, the operation instruction may also be determined according to a preset corresponding relationship between the cursor trajectory and the operation type, for example: if the mouse double-click is simulated, the track comparison determination can be carried out on the basis of the moving track of the cursor in the preset time period and the preset cursor track. How to aim at the operation instruction of the cursor is not limited too much.
And step S60, generating an interactive instruction according to the operation type corresponding to the operation instruction and the second coordinate information.

and step S61, determining an operation type corresponding to the operation instruction.
Step S62, determining the target object according to the second coordinate information.

In this embodiment, referring to fig. 8A, the laser coordinate is converted into a tocuh event to obtain a cursor, and therefore, the cursor has an attribute of tocuh, where touch includes three types of events, which are: touchstart, touchmove, touchend, wherein touchstart represents a trigger when a finger touches a DOM element. touchmove represents the trigger when a finger slides over a DOM element. Touchend identifies the trigger when a finger is removed from a DOM element. Therefore, the cursor can trigger a touch event, so that the cursor has a corresponding relation with an operation instruction (similar to the touch event).
For a target object to be operated (similar to the DOM element described above), the determination may be made according to the position of the cursor in the display interface, for example: when the operation type corresponding to the operation instruction is determined to be 'double-click' according to the cursor and the second coordinate information of the cursor corresponds to the 'music' application icon, the 'music' application program is taken as the target object, an interaction instruction for opening the music application program is further generated,
